The inability to mass-produce complex high-tech items is a known problem for Russia. It even effects chip production. For example, Russian flagship semiconductor company mikron.ru was not able to switch from 90 to 65nm for the last like 6 or 7 years. 65nm is still listed as experimental [1]. I thought that this was some kind of a corruption tax or barrier that made it impossible to scale the production, but given how widespread was this, I started to suspect that other factors were at play.
